Bill's Poster Shops Inc., has completed an analysis of weekly demand for its posters in three San Francisco-area outlets. Bill study revealed: Qx = 56,000 2000 Px + 5000 POP + 1000 Py R2 = .95 (2.39)* (3.5)* (3.67)* (2.6)* * t-statistics at .05 level Where Qx = annual poster demand; Px = poster price in dollars; POP = high school and college student population within a four-mile radius (in thousands), and Py = a price index of competitor poster prices in dollars. During this period a typical outlet had Px = $5, POP = 10000 and Py = $4 a. Explain a brief summary of what the equation results mean. b.
